Apache will not start: Cannot find /usr/local/apache/bin/litespeed

Symptoms

Apache will not start after the LiteSpeed license expires, and an error similar to the following will be in the logs:

CONFIG_TEXT: server.example.com restartsrv_httpd[1707233]: [ERROR] Cannot find /usr/local/apache/bin/litespeed

Cause

This issue occurs when the LiteSpeed license expires while it is running, which prevents LiteSpeed from switching to Apache. Reinstalling the ea-apache24-config-runtime package corrects this issue.

Resolution

1. Access the server's command line as the 'root' user via SSH or Terminal in WHM.

2. Reinstall the ea-apache24-config-runtime package:

   Almalinux 8/9, CloudLinux 8/9, Rocky Linux 8/9

   # dnf reinstall -y ea-apache24-config-runtime

   Ubuntu

   # dpkg --purge --force-depends ea-apache24-config-runtime

   # apt-get install ea-apache24-config-runtime

   CentOS 7, CloudLinux 6/7

   # yum reinstall -y ea-apache24-config-runtime

3. Switch the web server to Apache:

   # /usr/local/lsws/admin/misc/cp_switch_ws.sh apache
